Abstract
A screw includes a head part, a threaded part and a flexible connector between the head part and the threaded part for transmitting a torsional force between the head part and the threaded part, and to allow two bending movements between the head part and the threaded part in opposite directions in the longitudinal axis of the screw. The head part and the threaded part in each case have a longitudinal axis, which can be arranged offset in parallel to one another. The screw has an ε-modulus of between 20,000 and 100,000 N/mm2 against a rotation in the case of an arrangement of the head part and the threaded part on a longitudinal axis.
Claims15
A screw comprising a head part, a threaded part, and a flexible connector between the head part and the threaded part for transmitting a torsional force between the head part and the threaded part, and to allow two bending movements between the head part and the threaded part,
- wherein the head part has a head part longitudinal axis and the threaded part has a threaded part longitudinal axis, which can be arranged offset in parallel to one another with an offset,
- wherein the flexible connector has a first coupling element comprising at least two joint elements to transmit torsional forces among the at least two joint elements, and has a second coupling element fixedly connected to the head part and to the threaded part such that the second coupling element transmits tensional forces from the head part to the threaded part,
- wherein the first coupling element and the second coupling element are arranged concentrically to one another, and
- wherein the second coupling element is a rope, a cord or a chain and extends along a central longitudinal axis of the screw.
